WOODEN POST.

Application led April 9, 1908.

To all whom it may concern:

Be it known that l, JOSEPH CARPENTER, a subject of the King of Great Britain, residing in the town of Oak Lake, Province of Manitoba, Dominion of Canada, farmer, have invented certain new and useful Improvements in Wooden Posts, of which the following is a specification.

My invention relates to improvements in wooden posts, and the object of my invention is to protect the butt end of fence posts, telephone osts, telegraph posts, and wooden posts of all3 descriptions designed to be supported in the ground, from rot and decay; and a further object of my invention is to provide the butt end of my post with means for protecting it from fires that run along the ground, such as prairie fires, as hereinafter tmore particularly ex lained. gol Figure l is a side e evation of the butt end of a post constructed according to my invention, showing the same supported in the ground. Fig. 2 is a vertical central section through Fig. l, and Fig. 3 is a horizontal cross-section on the line a-b, Fig. l.

In the drawings, like characters of reference indicate corresponding parts in each iigure.

The butt end A of the post, is preferably peeled so as to remove the bark. Bored longitudinally through the butt end of the post upward, and preferably on a line with the center thereof, and of such length so that it will extend a suitable distance above the top of the ground, when the butt end is buried, is a Ventilating bore B.

O is a groove out in the outside of the post with which communicate the Ventilating pasisages D, D1 and D2 which open into the ven- 40 ltilating bore B and assist ventilation.

D2 and D4 are ventilating passages communicating with the upper portion of the Ventilating bore B and formed in the butt end A so as to be above the ground. The

45 Ventilating passage D2 communicates with the upper portion of the groove O.

D3 is a Ventilating passage opening from the side of the butt end into the Ventilating bore B.

It will of course be understood that the Ventilating passages may be of any desired number; the diameter of the same, together with the diameter of the Ventilating bore B may be varied in different sized posts, but 55 must always be of such size as to permit of the desired circulation of air. It will be no- Specification of Letters Patent.

Serial No. 426,149.

ticed that the said Ventilating passages open into the Ventilating bore B at an angle Although this construction is not essential, still it is preferable because in case any moisture gets into the Ventilating passages it will drain therefrom into the Ventilating bore B and thereoutof through its lower end.

E is a metallic sheathing, suitably secured as shown at E1, Fig. 3, to the butt end A. This sheathing may be made of any suitable metallic or other inoombustible material, but is preferably made of galvanized iron. The sheathing E is secured to the butt end A so that when the butt end is buried, the sheathing will extend a suitable distance above and below the top of the ground; the greater portion of its length being preferably below the ground. The sheathing E is preferably secured around the butt end A so as to provide a space E2 to permit circulation of air into and through the Ventilating passages; Ventilating bore B, and groove C. lt will be noticed that the sheathing E prevents the major portion of the length of the groove C from being filled up with earth.

F is a strip of any suitable material, such as iron or wood inclosing the lower portion of the groove O which is not protected by the sheathing E. The strip F is preferably secured in place, as by nails G, and extends a short distance underneath the lower portion of the sheathing E, and a suitable distance below the end of the groove C.

Fitting down over the top of the sheathing E is a metallic cap H, which is suitably secured to the post. This metallic cap increases the height of the metallic sheathing or envelop, and also acts as a covering for the upper Ventilating passages and the top of the groove O. The upper end of the cap H is preferably sunk into the wood so as to exclude moisture from getting between the same and the post. It will of course be understood that the cap H can be omitted, and the sheathing E extended up far enough to perform the function of the cap.

J are a plurality of longitudinal grooves formed in the outer surface ofthe butt end of the post, and preferably extend a suitable distance beyond the top and bottom of the sheathing E. The object of these grooves is to increase the circulation of air around the butt of the post.

From the foregoing specification, it will be understood that the Ventilating and the draining of the butt of the post will reduce the ercentage of moisture therein, and so will lncrease the life of the post. Experience shows that the butt of the post at and for a certain distance below the ground line rots and decays much more uickly than the remainder of the butt end. l ot only will the metallic sheathing protect the butt end from fires that run along the ground, but it will also assist the Ventilating bore and Ventilating passages to reduce the percentage of moisture therein.

It will of course be understood that I can omit the metallic sheathing and cap H without departing from the spirit of my invention.

What I claim as my invention is:

1. As a new article of manufacture, a wooden post, provided in its butt end with a Ventilating bore longitudinally formed therein, and a plurality of Ventilating passages opening from the outside of the butt end into the said Ventilating bore.

2. As a new article of manufacture, a wooden post, provided in its butt end with a Ventilating bore longitudinally formed therein, and a longitudinal groove formed in the outer surface of the said butt end, and a plurality of Ventilating passages connecting said Ventilating bore with said groove.

3. As a new article of manufacture, a wooden post, provided in its butt end with a Ventilating bore longitudinally formed therein, and a longitudinal groove formed in the outer surface of the said butt end, and a plurality of Ventilating passages connecting said Ventilating bore with said groove, and a metallic sheathing surrounding said butt end.

4. As a new article of manufacture, a wooden post, provided in its butt end with a Ventilating bore longitudinally formed therein, and a longitudinal groove formed in the outer surface of the said butt end, and a plurality of Ventilating passages connecting said Ventilating bore with said groove, and a metallic sheathing surrounding said butt end, and a metallic cap secured around the u per part of the butt end and. extending own over the top of said metallic sheathing.

5. As a new article of manufacture, a wooden post, provided in its butt end with a Ventilating bore longitudinally formed therein, and a longitudinal groove formed in the outer surface of the said butt end, and a plurality of Ventilating passages connecting said Ventilating bore with said groove; a metallic sheathing surrounding said butt end, and having its lower end supported above the bottom of said groove, and a sheathing or strip extending a suitable distance underneath thelower end of said metallic sheathing and down below the bottom end of said groove and placed over the lower portion thereof.

6. As a new article of manufacture, a wooden post, provided in its butt end with a Ventilating bore longitudinally formed therein, and a plurality of Ventilating passages constructed at an upwardly inclined angle, and opening from the outside of the butt end down into the said Ventilating bore.

7. As a new article of manufacture, a wooden post, provided in its butt end with a Ventilating bore longitudinally formed therein, and a plurality of Ventilating assages opening from the outside of the ffutt end into the said Ventilating bore; a plurality of Ventilating grooves longitudinally formed in the outside of said butt end, and a metallic sheathing surrounding said butt end, below and above the ends of which eX- tend the said plurality of grooves.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.
